ANDERS BCK, OF KORSNAS, GREAT KOPPARBERG, SWEDEN.

GOVERNOR `Foa STEAM-ENGINES.

SPECIFICATION forming' part of Letters Patent No. 261,980, dated August1, 1882.

Application led October 6, 1881. (No model.) Patented in Sweden March5,1881).

To all whom it may concern Be it known that I, ANDERS BCK, a citizen ofSweden, residing at Korsnas, in Great Kopparberg, Sweden, have inventeda new and useful Improvement in Governors for Steam-Engines, dtc.,`which improvement is fully'set forth in the following specification andaccompanying drawings, in which- Figure lisa side elevation, partlysectional, of the governor embodying my invention. Fig. 2 is ahorizontal section in line ww, Fig. 1.

Similar letters of reference indicate corresponding parts in the twofigures.

My invention consists of a governor which works with uniformity andsensitiveness, the construction and operation being hereinafter fullyset forth.

Referringto the drawings, A represents a vertical shaft, which issuitably mounted or supported and connected to a proper part of` theengine, so as to bc rotated thereby.

.B represents a sleeve, which is loosely t- 'ted' on the shaft A, andhas pivoted to it the arms of the'pendulnm-balls C G, said armsextending vertically, and having the balls C on the upper ends.

To the balls C are pivoted the lower ends of arms D, whose upper endsare pivoted to a cap, E, which latter is supported freelyon the top ofthe shaftA, so that the arms D, pendulum-balls C, and sleeve B aresuspendedfrom said cap E.

The wall of the upper part of the sleeve B has formed in it spiral waysa a, and the shalt A has secured to it a pin or pins, b, on which aremounted rollers F, which are so located that they project into said waysa a.

Keyed or otherwise tirmly secured tothe periphery ofthe sleeve B- is" abalancewheel@q weighted arms, G, said` wheel, in the present case,heilig secured' to the upper part of the collar, above the 'place ofconnection of the `pendulum-balls with said sleeve, the spokes of thewheel not interfering with the freedom of motion of said balls. Thesleeve is also formed with a neck, ci, with which engages the lever ofthe governorlvalve.

It will be seen that the outward movement v tion, instead of employingone sleeve andr one shaft, uses two sleeves and three shafts, besidestwo connecting-frames. My construction is much more simple and lessexpensive than this.

Having thus described myinvention,what I claim as new, and desire tosecure by Letters 1. A governor-shaft provided with a lateral pin, incombination with a sleeve which is adapted to move up and down on saidshaft, and provided with a spiral way that receives said pin,and a pairof governor-balls attached to said sleeve, and operating substantiallyas set forth.

2. A governor-shalt'provided with a lateral pin, in combination with asleeve which is adapted to move up and down on said shaft, and providedwith a spiral way that receives said pin, a fly-wheel attached to `saidsleeve, and a pair of governor-balls attached to said sleeve, andoperating substantially as set forth.

In witness whereof Ihave signedmy name in the presence of subscribingwitnesses.
